Description

Technical Field

[0001] The utility model relates to the technical field of hair dryers, in particular to a hair dryer with a double-layer shell. Background Art

[0002] The hair dryer is a hairdressing tool invented in the late 19th century. Modern hair dryers use electric means to accelerate the speed of air flow, thus generating wind and simultaneously increasing the air temperature. Hair dryers are mainly used for drying and shaping hair, but can also be used for local drying, heating and therapy in laboratories, physiotherapy rooms, industrial production, art, etc. According to the type of motor used, it can be divided into AC series-excited type, AC shaded-pole type and DC permanent magnet type. The advantages of series-excited hair dryers are large starting torque and high speed, which are suitable for manufacturing high-power hair dryers; the disadvantages are high noise and the commutator has certain interference with telecommunication equipment.

[0003] For example, a Chinese patent (CN219679982U) discloses a handheld hair dryer, comprising: a main shell body, on which an air outlet is provided; a handle cover plate, fixedly mounted on the main shell body, the handle cover plate comprising a main body portion and a fixing portion, and a connecting portion connecting the main body portion and the fixing portion, wherein the diameter of the fixing portion is smaller than the diameter of the main body portion, and the connecting portion is provided with a first air inlet connected to the air outlet; a handle sleeve, which is sleeved on the main body portion, and an abutting portion extending inwardly is provided on the inner wall of the handle sleeve, and the abutting portion is fixedly mounted to the connecting portion. The utility model provides a handheld hair dryer, which increases the electrical insulation strength and improves the air tightness of the inner space of the handle through the double-layer shell design of the handle portion, and at the same time, opens the first air inlet at the bottom of the handle, which not only ensures the ventilation and cooling effect of the entire device, but also keeps it away from the part held by human hands, thereby improving the safety of the operator when using it.

[0004] The above scheme still has the following technical deficiencies. The hair dryer in the above scheme has relatively simple functions. The hair dryer may cause certain damage to the hair when blowing air. However, users have increasingly higher requirements for hair protection. The above scheme is difficult to meet the needs of users to use essential oils to care for and maintain their hair while blowing their hair. Based on this, a hair dryer with a double-layer shell is proposed. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hair dryer with a double-layer shell, comprising a shell, a blocking mechanism and a dustproof mechanism are arranged inside the shell, four fixing rods are distributed in a circular array in the middle of the inner wall of the shell, an inner shell is fixed to one end of the four fixing rods away from the shell, an air inlet plate is fixed to the left side of the inner wall of the shell, two supporting rods are fixed to the right side of the inner wall of the shell, a first motor is fixed to one end of the supporting rod away from the shell, a blade is fixed to the output shaft of the first motor, a handle is fixed to the bottom end of the shell, an essential oil box is fixed to the top side of the inner wall of the shell, and the inner wall of the shell and the outer surface of the inner shell together form a cavity;

[0007] The blocking mechanism includes two vertical plates fixed on the bottom side of the inner wall of the shell, a second motor is fixed to the left side of the left vertical plate, a screw is fixed to the output shaft of the second motor, a baffle is threadedly connected to the outer surface of the screw, two limit blocks are fixed on both sides of the top and bottom ends of the baffle, and a first circular hole is opened inside the baffle.

[0008] Furthermore, the dustproof mechanism includes a dustproof plate slidably connected to the outer surface of the inner shell, the inside of the dustproof plate is abutted with two springs, one end of the spring is abutted with a movable plate, two sliders are fixed on the left and right sides of the movable plate, a mounting block is fixed on the end of the movable plate away from the spring, a handle is provided on the left side of the dustproof plate, and a second circular hole is provided inside the dustproof plate.

[0009] Furthermore, a bearing seat is fixed to the left side of the vertical plate on the right side, and the screw rotates in the bearing seat.

[0010] Furthermore, both sides of the top and bottom of the inner wall of the shell are provided with limiting grooves, and the limiting blocks slide in the limiting grooves.

[0011] Furthermore, movable grooves are provided on both the top and bottom sides of the dustproof plate, and the spring and the movable plate are located in the movable grooves.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The hair dryer with a double-layer shell is provided with a blocking mechanism inside the shell. When the essential oil box is not needed, the baffle plate cooperates with the shell to block the first circular hole to prevent air from passing through the cavity. When the essential oil box is needed, air can pass through the cavity to make the blown air carry the essential oil, thereby making rational use of the essential oil box. By providing a dustproof mechanism inside the shell, dust can be prevented from entering the cavity and the volatilization of the essential oil in the essential oil box can be reduced.
